Interesting Evaluating True Horsepower and CFM Ratings of Air Compressors

Is there a quiet air compressor?
 

If you put in a box you’ll need to force vent it or it’ll overheat. Look up “Rotary Vane Compressor”. Not cheap, but dead quiet and very high output.
Quincy makes a fine unit. https://www.aircompressorsdirect.com/Quincy-4152002723-Air-Compressor/p10831.html

You guys know damn well that California air compressor ain't gonna run no air tools. A air brush or a finish nail gun, that it.

That's the brand I did a search on. Very quiet.

The dry system is less than 100 gallons, so a small compressor that kicks on every so often will work.

It fills tires. Not much more. Not designed for heavy use. It is aluminum and easy to transport.

I use battery impacts. For high output I use PowerTank.

Now with all of that said, read the original requirement. Does not include high consumption tools.

My recommendation? Stay away from oil less. Not only are they objectively louder, their sound quality is much "harsher" than an oil type. I've owned the Makita MAC700 for years, and it's a powerful little workhouse. Decently quiet and trouble free.

Nonsense....I have a large tank in my garage, and picked up a small tank compressor for flooring projects and wanted something portable years ago. I don't use air tools that require a constant flow usually, so my small tank does great with all my nailers, powerful impact wrench, etc....90 psi is all that matters....rarely do I use my large tank any more...

I have used isolation feet under the compressor which helps. The big improvement I have made is to fab up a hose adapter and use radiator hose (and tube if it is a long run) to pipe the air inlet outside and put a protected air filter outside. That move most of the noise outdoors, which may not thrill your neighbors.
With the popularity of "cold air intakes" I have seen custom intake "kits" at the auto parts store, which might be easier than my solution with radiator hose.

You can also use compressed air or nitrogen in bottles for your dry system but there are some code requirements for monitoring pressure.
